lol, I'd say it is definitely an overgeneralization, but I've seen the culture they are referring to and it is very real and very irritating to deal with the messes they create. Don't read too much into it.

This is pretty close to what you'll see in the first paragraph of the Wikipedia article on brogrammer [1]. Klout posted an advertisement at the Stanford career fair saying "Want to bro down and crush some code? Klout is hiring."
